Background Info The state of the campus
telecommunications infrastructure
in December 2001
Status in December
• Slow speed 10MBS connection to the
desktop in offices and labs
• No connectivity in most classrooms
• Telephone switch and campus network
router in small room in underground
tunnel
• Data communications rooms shared
with other functions, such as electrical
equipment
Problems
• No physical room to expand telephone switch
or network router
• Lack of controlled access to data and
telephone equipment in shared rooms
• No space in conduits to pull in more cable to
add network and telephone connections
• Performance/speed issues on some network
segments
• Out of network ports on hubs in many
buildings
Luckily, a solution was on
the horizon - a CSU system wide project to
upgrade the campus data and
telephone infrastructure
Telecommunications
Infrastructure
Project
Bringing a 21st Century Network
Infrastructure to CSUDH
Project Overview
• Two stage, multi-phase project –
– Stage I – construction of Network Control
Center, new data communications rooms,
pathways, and cable system.
– Stage II – installation of network
management software, cable inventory
system, and upgraded network electronics
(switches).
Project Summary
• Duration: Feb. 18, 2002 - June 17, 2003
– extended through December 2003
• Buildings were upgraded in phases, starting
with the Student Health Center.
• Division coordinators/building captains were
main point of contact between building
occupants and project team.
Project Scope
• New Cat5e phone & data cable to all offices.
• New CISCO switches for included buildings.
• Gigabit ethernet on the backbone, 100Mbps
to the desktop and each classroom.
• All classrooms have at least 2 data
connections and a phone jack, and some will
be set up for future wireless access to the
network.
• Note: all old cable will be removed!
Project Scope continued
• Improved, dedicated communications
rooms (IDFs, BDFs).
• Campus telephone switch and network
router relocated to new facility that
provides extended UPS capabilities, fire
suppression, and room for growth.
• Generator provides power for 24 hours
in the event of a major outage.
Project Implementation
• Most inside work was done between 10pm
and 6am, so as not to disrupt campus
operations.
• Outside construction occurred during the day
(trenching, conduits, etc.)
• New network equipment (Stage 2) installed
after a building was completely re-cabled.
• Cutover by building (to new data & telephone
cable system).
Included Buildings
• Student Health Center
• ERC 1st floor, Theatre, LCH
• Gym, Field House, Hughes Center
• NSM, CP, PP, SBS, SOE
• SCC buildings 6 - 11
• SCC buildings 1-5
What about the other buildings?
• Welch Hall – meets specs – recent
construction..
• ERC floors 2-5 - will be remodeled in the
future (buying new switches as funding
permits).
• SAC 1,2,3 - older CISCO switches will be relocated from buildings covered by this project.
• USU - covered by building addition project.
• EAC - meets specs - recent “construction”.
Network Electronics
• Campus core switch - CISCO 6509
(replaces CISCO 8540 router)
• Building switches - CISCO 6509 or
CISCO 4006.
• Within building switches - most are 24
or 48 port CISCO 2950s
CISCO Catalyst 6509
• Enterprise/building switch
• Scalable platform
• 9-slot modular chassis, 1 slot reserved for
supervisor engine
• Switching backplane - up to 32 Gbps
• Gigabit ethernet interface to other switches
• Supports up to 384 10/100 ethernet ports
• Routing capability (Layer 3)
CISCO Catalyst 4006
• “Branch office”/building switch
• 6-slot modular chassis, 1 slot reserved
for supervisor engine
• Supports up to 240 10/100 ports
• Layer 3 routing capability
CISCO Catalyst 2950
• 24 or 48 port fixed-configuration,
stackable switch, 2 GBIC uplink ports
• Note - we are not stacking them - all will
have a GBIC uplink to building
switch/backbone connection
• MTBF prediction - 159,026 hours (in
other words, they are very reliable)
Network Design
• No change in topology (star).
• Completely new parallel network.
• Temporary “bridge” between Cisco 8540
router and new Cisco 6509 core switch
to tie old and new networks together
until the end of the project.
Network Design (continued)
• All IDF switches will have “home run” fiber
connection to BDF switch (no “daisy chains”).
• All BDF switches will connect back to core
campus switch in ERC via Gigabit ethernet
over fiber.
• Capability for redundant connections will be
in place - will be implemented as funds are
available.
More Network Design Info
• IP only protocol on new network - no
IPX, DECNET, LAT, Appletalk, etc.
• Implementing private IP numbers - all
155.135.XXX.XXX numbers will change
to XXX.XXX.XXX.XXX.
• Network address translation will be
done at the campus border firewall ( we
are purchasing a 2nd firewall).
INTERNET
155.135.1.1 (DHVX20.CSUDH.EDU)
CAMPUS FIREWALL
XX.XX.XX.XX (DHVX20 INTERNAL #)
Benefits to CSUDH
• Ability to deliver video and multimedia
applications to classrooms and offices.
• Ability to support next generation
applications such as Voice over IP,
wireless technologies, and PeopleSoft
Student Record system.
• Ability to rapidly adapt to changing
technologies over the next few years.
More benefits
• A more reliable, easier to manage
campus network that is ten times faster
(100 Mbps vs 10Mbps).
• Ability to detect and respond to network
problems in a timely manner.
And more ….
• Safer, more secure data
communications rooms that meet
standards.
• Support for additional telephone and
network installations in new Network
Control Center as buildings are added
and services expanded.
